Identity stackpowering secure data exchange
A scalable, secure, and fully managed technology stack for building user-centric identity solutions and trusted data exchange
The Problem
Building user‑centric identity and trusted data exchange is too complex
Identity workflows are too fragmented
Businesses are expected to offer passwordless onboarding, consent‑driven data exchange, and seamless interoperability across ecosystems, while also minimising data collection and keeping up with evolving open standards like VCs, DIDs, and OID4VP.
Developers lack a unified toolkit
Teams end up stitching together authentication, wallets, VC issuance and verification, schemas, messaging, and consent tooling - all while carrying the heavy burden of security, scalability, and compliance.
Complexity slows teams down
The result is long lead times, higher risk, and fragmented user experiences. What's missing is a fully managed, interoperable, privacy‑by‑design stack that removes this complexity and lets teams move from idea to production quickly and securely.
The Solution
Why build with Affinidi Elements
Affinidi Elements gives you everything you need to build secure, user‑centric identity experiences powered by open standards.
Privacy and consent by design
End users share only what's needed through open standards like OID4VP, reducing your data liability while streamlining compliance.
Developer‑friendly
Spin up projects in the Affinidi Portal and Affinidi CLI, integrate with TDKs/SDKs, and accelerate development with ready‑to‑use reference applications.
Interoperable out of the box
Built on W3C Verifiable Credentials (VCs) and Decentralized Identifiers (DIDs) for trust that works across vendors, platforms, and ecosystems.
Features
Affinidi Elements product capabilities
Explore the comprehensive suite of products and tools within Affinidi Elements, designed to empower developers in building secure, user‑centric identity solutions with W3C Verifiable Credentials and Decentralised Identifiers.
User-controlled identity infrastructure
The Internet of Trust requires identity systems that allow users to maintain control over their data and choose what to share. Our identity vault infrastructure provides the components for building self-sovereign identity applications.
Affinidi Vault
User-controlled credential storage
Digital wallet enabling users to securely collect, store, and share verifiable credentials with granular consent controls using OID4VCI and OID4VP protocols.

Decentralised identity implementation toolkit
Comprehensive libraries and tools for building decentralised identity capabilities across platforms.
Explore More →DCQL
Digital credentials query language
A standardised query interface that enables verifiers to request specific credentials from user wallets, supporting credential sharing and selective disclosure.
Explore More →Affinidi TDK – Vault
Provides libraries and tools for embedding Affinidi Vault into your existing Dart applications, implementing Self-Sovereign Identity (SSI) for decentralised identity management.

A Simple, Secure Flow for Verifiable Credentials
A seamless issue-store-share-verify flow, built on open standards.
1
Issue
Issue tamper-proof Verifiable Credentials using the OID4VCI standard.
2
Store
Users securely store their credentials in the Affinidi Vault.
3
Share
Users share credentials through consent‑driven sharing via Affinidi Vault.
4
Verify
Instant, cryptographic verification of VCs/VPs. No issuer round‑trip.
Use Cases
Build business friendly use cases
Practical patterns for building user‑centric, privacy‑first applications across authentication, messaging, and verifiable credentials.
Passwordless authentication with Affinidi Login
For consumer apps, marketplaces, membership communities, and events where you want one‑click registration and login, with the option to request only what you truly need (e.g. email, phone number, or age over 18).
Secure and private messaging
Build next-gen communications where people, organisations, and AI agents discover, connect, and exchange data using Decentralized Identifiers (DIDs) over DIDComm with end-to-end encryption and privacy-preserving server routing.
Issue verifiable credentials (VCs)
For events, certifications, memberships, and employability proofs. Generate cryptographically signed, tamper‑evident credentials that are portable and reusable across services, with sub‑second verification.
Verified onboarding and KYC-lite
Request only the facts you need (e.g. age over 18) with verifiable presentations (VP) via Affinidi Iota. Stop storing excess PII and reduce your data liability.
Employment credential verification
Upgrade background checks to reusable, verifiable credentials. Built on open standards, they deliver cryptographic authenticity and consent‑based selective disclosure, so HR teams confirm only what's needed.
In-app credential wallet for end users
Let end users securely store and share VCs in your app. Use Affinidi Vault (web) for instant onboarding, or embed Vault capabilities directly into your Flutter app with the Affinidi TDK Vault for Dart.

The Difference
Proprietary identity vs. open standards
Why developers choose Affinidi Elements.
| Category | Proprietary Identity | Elements (Open Standards) |
|---|---|---|
| Portability | Locked to vendor format. Migration = rebuild everything. | W3C VC standard. Use any compliant provider. Switch freely. |
| Verification | API calls to vendor. Rate limits. Downtime = no verification. | Local cryptographic verification. Works offline. Infinite scale. |
| User Control | Vendor stores user data. You're liable for breaches. | Users own credentials in their wallet. Zero PII storage. |
| Compliance | Centralised data = GDPR liability. User deletion nightmares. | Privacy by design. User controls data. Compliance built-in. |
| Integration | Proprietary SDK. Vendor-specific APIs. No interop. | Open standards (W3C, OID4VCI, DIDs). Works everywhere. |
| Pricing | Vendor lock-in pricing. 3-5x increases post-contract. | Transparent pricing. No lock-in. Self-host option. |
